[Mailman-Users] Mailman under Fedora Core 2

Using Sendmail, SMTPDirect, on the same machine as mailman.. nothing 
logged in /var/log/maillog aside from normal email processing.. And 
nothing in /var/log/messages, and plenty of disk space all around..

All of our mailman logs are in /var/mailman/logs, and that's my only 
indication of the problems I attached initially..

However.. I did find something of interest.  It seems that the major 
backlog of messages I had were about 80-100 bogus messages.  What I 
mean, is that they were all dated about 3-5 months old.  I removed them 
completely (they kept appearing in the "out" directory, then they would 
get moved to the "shunt" directory, then back again depending upon 

Additionally, I set up Nagios to monitor the number of items in the 
"out" directory just to see if anything gest hung.. things look good so
